Fixing your battery life is easy:
- Install a replacement battery, easily available online (and cheap).
- Replace Facebook.app with the mobile web version.

For $15 and 20 minutes, it’s super nice.
* According to certain reports iOS devices are produced in less than ideal conditions. In fairness, I hear things are improving of late.
